Senior Full-Stack Engineer

EMEA (Remote)

Senior Level

WHAT YOU'LL DO:

Platform Engineering

  • Build intuitive, performant frontends in React and JavaScript, and develop scalable backend services, APIs, and data pipelines in Java to support AI agents and automation workflows.
  • Contribute to building the orchestration layer for our platform, enabling autonomous multi-step actions across integrated tools and third-party platforms.
  • Integrate LLMs and AI agents into the web platform, including connecting to RAG-backed services.
  • Work with the Model Context Protocol (MCP) to connect agents to external APIs and databases.
  • Contribute to architectural decisions and developer experience improvements as an early member of the platform team.

AI quality engineering

  • Contribute to evaluation pipelines and quality checks for LLM outputs, and integrate automated tests into the deployment pipeline.
  • Build automated test suites and quality gates so regressions are caught before production.

Infrastructure & reliability

  • Build and maintain cloud-native infrastructure with containers and CI/CD pipelines.
  • Ensure all systems are production-grade: comprehensive error handling, logging, alerting, and observability.

‍

WHAT YOU BRING:

  • Engineering experience: 5+ years designing, building, and shipping full-stack products end-to-end — from database to frontend — in collaborative environments.
  • Coding proficiency: Proficiency in Java (Spring Boot), React, and JavaScript, with a focus on clean, maintainable, and testable code.
  • Database knowledge: Solid understanding of how to design scalable, reliable data flows. Experience with PostgreSQL, Elasticsearch, or cloud data warehouses (BigQuery or similar); familiarity with vector databases (e.g., Qdrant, Pinecone) is a plus.
  • API & infrastructure: Strong experience with REST APIs, Webhooks, and secure API design. Comfortable with AWS (S3, EC2) and cloud-based deployments.
  • Quality mindset: You care deeply about measuring what you build. Solid experience with CI/CD pipelines and automated testing. Curiosity about measuring AI output quality — experience with LLM eval tools is a plus.
  • LLM & RAG familiarity:
    • Comfortable working with LLM APIs (OpenAI, Anthropic, Gemini) including prompt engineering, tool/function calling, and structured outputs.
    • Familiar with agentic frameworks or orchestration tools such as n8n, LangChain, or similar.
    • Familiar with RAG systems and embeddings concepts.
  • Engineering practices: Strong grasp of modern software engineering — version control, peer reviews, observability, and a collaborative, curious mindset.
